Ribbed centerbulb is the most versatile type of waterstop available. The centerbulb accommodates lateral, transverse, and shear movement. Ribbed centerbulb can be used in expansion, construction, and control joints. Ribbed centerbulb waterstops provide superior anchoring abilities and a long fluid-flow path because of the multiple ribs on the exterior flanges. Under stress, the multiple ribs will distort less than a dumbbell type waterstop. This is because the stress is first applied to the inward-most anchoring rib, and decreases to the subsequent ribs. The centerbulb allows for joint movement beyond the ultimate elongation of the material (530%), without causing distortion to anchoring ribs. All of our ribbed centerbulb waterstops are manufactured with a large outer diameter centerbulb. This centerbulb, coupled with the outstanding mechanical properties of our proprietary TPV elastomer (ultimate elongation, tensile strength, etc.), provides for unsurpassed joint movement and sealing abilities. Like all our thermoplastic vulcanizate waterstops, Earth Shield ribbed centerbulb waterstop can be heat-welded using a standard waterstop splicing iron. This allows for easy field fabrications, and allows the waterstop to function as a continuous, homogeneous, fluid-tight diaphragm. Waterstop change of directions can be purchased along with straight roll stock, and custom, fit-to-print waterstop modules are produced to order. Prefabricated ells, tees, tank pads, column fittings, and many others are in stock and ready to ship.

Retrofit waterstop is designed to provide a fluid-tight seal between existing and new concrete construction, without resorting to the labor-intensive and structurally destructive saw-cut-and-grout method. It is ideal for constructing a new containment curb or wall to an existing slab, or joining a new slab to an existing wall. Special profile fabrications are available for columns and pipe penetrations. All of our retrofit waterstops are sold as a complete system, and include all the necessary stainless steel bars and bolts. We also offer a high-quality chemical resistant novolac epoxy — VEN 1000. Earth Shield retrofit waterstops are manufactured with our proprietary thermoplastic vulcanizate compound, which provides for unsurpassed chemical resistance. Like all our thermoplastic vulcanizate waterstops, Earth Shield retrofit waterstop can be heat-welded using a standard waterstop splicing iron. This allows for easy field fabrications, and allows the waterstop to function as a continuous, homogeneous, fluid-tight diaphragm. Waterstop change of directions can be purchased along with straight roll stock, and custom, fit-to-print waterstop modules are produced to order. Prefabricated ells, tees, tank pads, column fittings, and many others are in stock and ready to ship.

Integrated expansion board cap waterstop systems are designed to replace post-applied joint sealant, and provide a fluid-tight internal seal like a traditional waterstop with a one-step, integrated unit. Earth Shield expansion board cap waterstop is installed on top of conventional expansion board filler or Earth Shield’s own chemical resistant, plastic expansion board. The expansion board acts as the form; therefore, no form splitting is necessary. This greatly accelerates the project schedule and provides a long lasting, attractive finished concrete joint. Earth Shield screed key cap slides over the top of metal screed key, eliminating the need for sealant. Like all our thermoplastic vulcanizate waterstops, Earth Shield integrated cap system waterstop can be heat-welded using a standard waterstop splicing iron. This allows for easy field fabrications, and allows the waterstop to function as a continuous, homogeneous, fluid-tight diaphragm. Waterstop change of directions can be purchased along with straight roll stock, and custom, fit-to-print waterstop modules are produced to order. Prefabricated ells, tees, tank pads, column fittings, and many others are in stock and ready to ship.

Earth Shield tear web waterstops are designed for large joint movements such as tank foundations. Tear web is suitable for expansion joints. For construction and contraction (control) joints, ribbed centerbulb should be used instead. We also manufacture a retrofit product specifically designed to accommodate large shear movements, such as tank ring foundations subjected to settlement. The JP621L Retrofit Waterstop System is chemically and mechanically adhered to the existing concrete using one of our chemical resistant, novolac epoxies (VEN500 or VEN1000), stainless steel batten bar, and stainless steel anchor bolts. New for 2010, Earth Shield part number JP540L is designed to act as an external, post-installed, retrofit waterstop seal, ideal for sealing between walls and slabs. Like all our thermoplastic vulcanizate waterstops, Earth Shield tear web and large movement retrofit waterstops can be heat-welded using a standard waterstop splicing iron. This allows for easy field fabrications, and allows the waterstop to function as a continuous, homogeneous, fluid-tight diaphragm. Waterstop change of directions can be purchased along with straight roll stock, and custom, fit-to-print waterstop modules are produced to order. Prefabricated ells, tees, tank pads, column fittings, and many others are in stock and ready to ship.

Base seal waterstop is ideal for flat pavement jobs such as runways, large containment slabs, etc. Base seal waterstop is by far the easiest waterstop to install... Simply lay the waterstop directly on the compacted subgrade, place and finish concrete, and create control joint using saw cut or other method. The base seal provides a permanent, life-of-structure seal at the bottom of the joint. Base seal is suitable for construction, contraction (control), and expansion joints. Base seal should not be used on jobs that make interior wall transitions as the part is non-symmetrical and therefore cannot function correctly. For large hydrostatic head pressures (>50 foot) ribbed centerbulb should be used instead. Like all our thermoplastic vulcanizate waterstops, Earth Shield baseseal waterstop can be heat-welded using a standard waterstop splicing iron. This allows for easy field fabrications, and allows the waterstop to function as a continuous, homogeneous, fluid-tight diaphragm. Waterstop change of directions can be purchased along with straight roll stock, and custom, fit-to-print waterstop modules are produced to order. Prefabricated ells, tees, tank pads, column fittings, and many others are in stock and ready to ship.

Dumbbell waterstop is usually used in below grade applications, where limited movement is expected. Dumbbell waterstop can be installed in construction and contraction (control) joints; whereas, dumbbell centerbulb can be installed in construction, control, and expansion joints. The large centerbulb (1-1/2” outer diameter) on the JP949 (and JP1149) waterstop profile, coupled with the outstanding mechanical properties of our thermoplastic vulcanizate and large endbulb anchors, enable the product to withstand large-scale joint movement (seismic, settlement, etc.). JP648, JP948, JP949 and JP1149 are all 3/8” thick... The largest and thickest profiles available in the industry! Like all our thermoplastic vulcanizate waterstops, Earth Shield dumbbell waterstop can be heat-welded using a standard waterstop splicing iron. This allows for easy field fabrications, and allows the waterstop to function as a continuous, homogeneous, fluid-tight diaphragm. Waterstop change of directions can be purchased along with straight roll stock, and custom, fit-to-print waterstop modules are produced to order. Prefabricated ells, tees, tank pads, column fittings, and many others are in stock and ready to ship.

Flat Strip waterstop is usually used in below grade applications, where limited movement is expected. Flat strip waterstop can be installed in construction and contraction (control) joints. Both JP637 and JP937 are all 3/8” thick... The largest and thickest profiles available in the industry! Like all our thermoplastic vulcanizate waterstops, Earth Shield flat strip waterstop can be heat-welded using a standard waterstop splicing iron. This allows for easy field fabrications, and allows the waterstop to function as a continuous, homogeneous, fluid-tight diaphragm.
